American hedge fund Starboard Value has acquired a 9.3% stake in Green Dot, a financial firm known for issuing prepaid cards in the US.
In a regulatory filing, the New York-based hedge fund said that it is mulling to bring operational changes in order to improve the performance of Green Dot.
Green Dot’s stock plummeted last year due to an onslaught of competition from a new generation of financial technology ventures.
Green Dot in a statement said: “Green Dot’s board of directors welcomes transparent, constructive feedback regarding the common goal of enhancing long-term shareholder value.
“The company appreciates all shareholder relationships, and will remain focused on executing its business strategy and maximising value for all shareholders.”
Selling prepaid debit cards is the core business of Green Dot. Its prepaid cards can be loaded at stores by customers who may not have a traditional banking relationship.
